CASH-R SPECIFICATION forming part of Letters OF DETROIT, MICHIGAN.

EGIVSTER.

Patent No. 434,374, dated August 12,1890.

Application filed January 11 1890. Serial No. 336,612. (No model.)

To all whom it may concern:

Be it known that I, HERBERT T. BRADLEY, a citizen of the United States,residing at Detroit, county of IVayne, State of Michigan, have inventeda certain new and useful Improvement in Cash Registers and Indicators;

- and I declare the following to be a full, clear,

reference being had to the accompanying drawings, which form a part ofthis specification.

My invention is designed to produce a cash register and indicator whichshall be positive in its operation and yet simple in construction; andit consists of a combination of devices and appliances hereinafterdescribed and claimed.

In the drawings, Figure 1 is a perspective View of the exterior of mymachine. Fig. 2 is a vertical section of the same. Fig. 3 is ahorizontal section with the parts in elevation. Fig. 4 is an elevationof the key-table. Fig. 5 illustrates the mechanism for operating thetable. Fig. 6 is a perspective View illustrating a portion of themechanism; and Fig. 7 is a detail perspective View of the arms foroperating the table or carriage by sliding the drawer.

. In carrying out my invention, A represents the case of my machine.

B is a series of operating-keys adapted to be struck by the operator inrecording a sale. Each key represents one of the digits, and there isalso a key for the 0. Each key has a shank b, which extends down intothe case,

the lower end entering and playing in the bar B which extends across themachine. The keys are thus supported so that they can have a freevertical movement.

0 are levers extending from front to rear of the case and supported bythe bar 0', which extends across. To the front end of each of the leversG is pivoted one of the keys, as at b, the engagement being such that asthe key is struck the rear end of the lever will be thrown up. On thisrear end is a transverse slot or opening 0.

D is what may be termed a movable table or carriage, and on this tableor carriage the recording type-levers E are mounted.

These type-levers are preferably shaped, as shown in Fig. 2, in the formof a bell-crank, and are pivoted to the table or carriage at e. Thelower or short arm 6' extends down and enters the slot 0. 0n the end ofthe upper or long arm 6 is the projectionc containinga recording-typecorresponding with the figure on the corresponding actuating-key B.These type-levers E are all set at such an angle that when actuated theprojection e of each typelever will pass through the orifice d of thetable or carriage.

F is a roll of paper, and G is a roll on which the paper is wound afterthe recording has been done. Between the two is what may be termed astationary platen H. The projection passing through the orifice, thetype strikes the paper and records the figure.

d is an inking-roller mounted on the spring d and adapted to ink thetype just before it strikes the paper. I

I will now describe the mechanism whereby a motion is imparted to thetable or carriage. I is a universal bar extending across the machineunderneath the levers O and back to the rear of the machine. This bar ispivoted at 1'. J is a wheel or drum pivoted to the table or carriage Dand provided with the spring J. J is a rack-bar attached to the case. Aportion of the periphery of the drum or wheel J is provided with theteeth j, adapted to mesh with those on the rack-bar, while the balanceis provided with the ratchet-teet-hj. J 3 is an escapement-lever pivotedat j to the table. This escapement-lever is connected by the rod J 4with the rear end a" of the bar I, and the construction is such that theraising of the rear end of the bar I operates the escapement-lever J sothat the pawl 7' on the lower end engages in the ratchets and preventsthe revolution of the wheel. Then when the bar I is lowered the wheel ordrum J, through the spring 'J, will be revolved until the upper end 3'engages in the next ratchet-tooth. The pawls j j may be pivoted on theescapement-lever J 3 to render the ratchet; but the pivoting of thepawls is not indispensable. The wheel meshing with the rack-bar willthus move the tab e the space of one ratchet eachtime the front end ofthe bar I is depressed, "or, in other words,

them more capable of engaging and releasingeach time a key is struck.Thus if the operator wishes to record a sale of twenty-five dollars andthirty-seven cents he strikes first key No. 2. This operates, throughthe lever C and key E, to record on the paper ribbon the figure 2, andwhen the actuating-key is released the table, through the medium of therack-bar J wheel J, and spring J, is moved along one space, ready forthe figure 5 to be recorded, and so on until all four figures have beenrecorded.

I will now describe the mechanism for moving the paper: K is a barextending from front to rear of the machine, the front end pivoted at 70to the end of the universal bar I, while the bar is fulcrumed at 70,being movable horizontally on this fulcrum. A spring 70 serves to keepthe bar in the position shown in Fig. 3 until moved by exterior means. Kis an arm or red extending down from the carriage or table adjacent tothe bar K, so that as the table moves to the right when the key isreleased it carries the bar K with it. L is a vertical rod supported atZ, the lower end being in such position that as the bar K is forced tothe right by the table or carriage it will be under the end of the rod Lafter the key for the next to the lastfigure is struck and released, asillustrated in Fig. 6. Now when the last key is struck the depression ofthe front end of the bar K acts to force up the vertical rod L. M is asmall pivoted lever or pawl having the pivoted segment at on its end. Mis a ratchet-wheel keyed to-the shaft of the drum on which the paper iswound. Now when the last key is struck, as before explained, and the rodL raised, it presses against the lever M and drops the segment m downunder the next tooth. Then the release of the key and lowering of therod allows the spring M to bear on the lever M and move the wheel onespace. This moves the paper up opposite an opening in the case, so thatit can be seen from the exterior, and by placing the lens M in the casethe figures will be enlarged, so that they can be plainly seen. Thesegment m is pivoted and arranged as shown to enable it to yield andmove down past one of the teeth of the ratchet-wheel M, so as to beplaced under such tooth 'for turning the ratchetwheel one tooth when therod L descends.

I will now describe the mechanism for operating the cash-drawer and forreturning the table or carriage to its normal position after a sale hasbeen recorded. N represents the drawer, and N is a spring placed behindit for throwing it out when released. 0 is a small latch pivoted to thecase, having on its under side a beveled projection 0, adapted to engagein a notch on the side of the drawer. The side of this latch also has aprojection 0, under which the bar K is forced by the last movement ofthe table or carriage, as shown in Figs. 3 and 6. Thus the striking ofthe last key operates to raise the latch O and release the drawer, whichis forced open by the spring. P is an arm extending from the side of thecase above the drawer and supports on its outer end a vertical pivot.Keyed to the upper end of this pivot is the arm P, adapted to bear onthe arm or rod K, which is attached to the table, and keyed to the lowerend is the arm P extending horizontally to the edge of the drawer. P isa pin or projection on the drawer adapted to strike the arm P As thedrawer is thrown out, this pin or pro jection strikes the arm P andrevolves it until it has passed, when the spring 19 throws itarounduntil the arm P bears on the rod K. Now as the drawer is closed this pinor projection, bearing on the arm P causes the arm P to move the tableback until the pin has cleared the arm P The table is thus thrown overready to have another sale recorded, and the spring serves to return therod K to its normal position.

I have heretofore explained the manner of recording a sale the amount ofwhich contains four figures. In order to provide for recording a sale ofless than four figures, the space-key B is provided. This key makes norecord, but simply acts on the universal bar and moves the table. Thusif one dollar and eighty-eight cents are to be recorded the operatorstrikes the space-key first, then 1, 8, 8; if twenty-five cents, hestrikes the space-key twice, then 2, 5; if seven cents, he strikes thespace-key three times, then 7.
